1.1.1 Intended use The rotary module series CR 12 / CR 16 / CR 20 is used for the rotary movement of rigidly mounted loads in non-explosion hazardous ambient and deployment conditions that are suitable for this module according to these Installation Instructions.
NOTE Consider please! This leaflet should be read by every person who comes into contact with the module. CR 12 - CR 16 - CR 20 - BA-vers.4.0 gb 20190630...
Montage Instructions or have not been approved in writing by Afag Automation AG are not permitted. In case of improper changes or assembly, installation, operation and maintenance or repairs Afag rejects all liability. CR 12 - CR 16 - CR 20 - BA-vers.4.0 gb 20190630...
3.1.2 General description This is an incomplete machine The series of the CR 12 / CR 16 / CR 20 Rotary module is used for the linear, smooth movement of rigidly mounted loads under the ambient and Installation conditions defined, see Technical data.
CAUTION The CR is designed exclusively for the rotational movement in any required position with a torque of 0.45 Nm for CR 12 and 1.25 Nm for CR 16 and 2.2 Nm for CR 20 which, when handled, do not react in a way which could endanger persons, objects or the environment.
When connecting compressed air for the first time make sure that all air throttles are closed. Aerate the system slowly. CR 12 - CR 16 - CR 20 - BA-vers.4.0 gb 20190630...
Wear parts (e.g. shock absorbers) are not covered by the warranty. * The warranty covers the replacement or repair of defective Afag parts. No further claims will be accepted. The warranty will be voided in event of the following: ...
The CR module is equipped with 5 air connections depending on the direction of rotation. Upper half of module, 5 air connections, clockwise direction. Lower half of module, 5 air connections, counterclockwise direction CR 12 - CR 16 - CR 20 - BA-vers.4.0 gb 20190630...
7 Flow control valve to damping of the intermediate position 4 One –way restrictor 3/2 Directional control valve NOTE Minimal compressed air quality to ISO 8573-1; 2010 (7-4-4) CR 12 - CR 16 - CR 20 - BA-vers.4.0 gb 20190630...
Make sure that there are no persons or tools within the operating range of the module. Carry out a test run at first at slow traverse speed, afterwards under operating conditions. CR 12 - CR 16 - CR 20 - BA-vers.4.0 gb 20190630...
5. Turn the forward and backward position of the stop sleeve 3 at the hexagon of the stop sleeve until the end position is correct. 6. Tighten clamping of the stop sleeves by tightening the clamping screw 4. CR 12 - CR 16 - CR 20 - BA-vers.4.0 gb 20190630...
CAUTION If the angle of rotation is reduced by much more than 95° air may leak for constructional reasons. Turn the stop screw back to remove the leakage CR 12 - CR 16 - CR 20 - BA-vers.4.0 gb 20190630...
The threaded sealing ring must be screwed onto the shock absorber. Pushing the threaded sealing ring over the shock absorber will damage the sealing lips and cause the module to leak. CR 12 - CR 16 - CR 20 - BA-vers.4.0 gb 20190630...

Please note: When removing or mounting a shock absorber ensure that the sealing ring fits close to the stop sleeve before tightening the locknut. CR 12 - CR 16 - CR 20 - BA-vers.4.0 gb 20190630...
At the CR-rotation modules with intermediate position must on the ZP-side exhaust throttle must be installed. With the throttle can the damping behavior of the intermediate position is be regulated will. CR 12 - CR 16 - CR 20 - BA-vers.4.0 gb 20190630...
Polling of the stop positions is monitored by an LED on the initiator. If the LED switch status does not change during polling the Sensor is faulty and must be replaced! Magnetic field sensors PNP proximity switch (magnetic) Order No. 50033432 CR 12 - CR 16 - CR 20 - BA-vers.4.0 gb 20190630...
3. Control test with rotating module if the sensor switches 4. Position of the rotary engine set 5. Sensor to the desired position 6. Sensor with the screw (3) tighten CR 12 - CR 16 - CR 20 - BA-vers.4.0 gb 20190630...
Two C-grooves each are also located on both sides of the intermediate module (CR - ZA). Here, the intermediate position(s) is (are) polled by one magnetic field sensor. CR - ZA CR 12 - CR 16 - CR 20 - BA-vers.4.0 gb 20190630...
Under the following conditions is the CR-rotary module maintenance free: Clean workshop atmosphere No splash water No dust and fumes caused by abraison or processes Ambient conditions according the technical catalog CR 12 - CR 16 - CR 20 - BA-vers.4.0 gb 20190630...
Module inserts for ionized air environments (e.g. in case of high- voltage procedures such has corona processes) Open guides and piston rods should be covered with a grease layer to avoid formation of rust. CR 12 - CR 16 - CR 20 - BA-vers.4.0 gb 20190630...
4.1.4 Disassembly and repair When the module is damaged it can be returned to Afag Automation AG for repair. CAUTION The module may only be disassembled when the system is aerated and deactivated. If pneumatic connections are disconnected when they are under pressure, this may result in serious personal injury due to fast movements of moving parts.
